I was looking for a pack that would hold a reasonable amount of stuff, as I do a fair bit of walking. I used this pack recently walking the Mawddach Trail, approx 10 miles, and it was superb. I have used various brands of rucksack before and this one more than meets the requirements! The waist strap is a massive bonus for a bag of this size in my opinion, and certainly reduced the stress on the shoulders! Lots of pockets/storage, I kept the first aid stuff in the bottom pocket, snacks in the front, spare jacket in the main pack and plenty of room for more. Oooh and water bottles in the side pockets too. A very nice surprise was the zip just under the pocket at the bottom, where a waterproof cover was hiding. I wish other backpacks would use this type of cover, mainly because it's attached to the main pack (very useful in windy Welsh weather.....) An excellent bag, would highly recommend!!
